Neurodevelopmental Disorders

Neurodevelopmental Disorders

Introduction

• Neurodevelopmental disorders are less easily diagnosed in children than adults.

• Reasons for difficulty in diagnosis:

  • Lack of abstract cognitive abilities

  • Limited verbal skills

  • Constant state of change and development

• Common issues in children include:

  • Mood disorders

  • Anxiety disorders

  • Eating disorders

• Disorders are typically diagnosed in infancy, childhood, and sometimes in adolescence.

Intellectual Disability

• Defined as below-average intellectual functioning with an IQ of less than 70.

• Accompanied by significant limitations in various areas, including:

  • Communication skills

  • Self-care abilities

  • Home living skills

  • Social/interpersonal skills

  • Work skills

  • Leisure abilities

  • Health and safety awareness

Causes of Intellectual Disability

• Contributing factors include:

  • Heredity (genetic factors)

  • Altered embryonic development

  • Maternal consumption of alcohol during pregnancy

  • Perinatal issues (events occurring around the time of birth)

  • Medical conditions during infancy

  • Environmental influences affecting development

Autism Spectrum Disorders

• Characterized by severe impairment in:

  • Reciprocal social interactions

  • Communication skills

  • Restricted and stereotypical behavioral patterns

• Types of Autism Spectrum Disorders include:

  • Autism (classic autism)

  • Rett’s disorder

  • Childhood disintegrative disorder

  • Asperger’s disorder

Features of Autism

• Symptoms usually present by early childhood and are more common in boys than girls.

• Includes:

  • Little eye contact

  • Few facial expressions

  • Limited use of gestures for communication

  • Challenges relating to peers and parents

  • Lack of spontaneous enjoyment

  • Apparent absence of mood and affect

  • Inability to engage in play or imaginative activities with toys

  • Little intelligible speech

  • Stereotyped motor behaviors (e.g., hand flapping, body twisting, head banging)

Causes and Treatment of Autism

• There is a genetic link to autism; controversy exists regarding the MMR vaccine.

• While traits may improve, symptoms can persist into adulthood.

• Treatment goals include:

  • Reducing behavioral symptoms

  • Promoting learning and development

• Recommended interventions include:

  • Special education

  • Language therapy

  • Medications for specific symptoms

Types of Autism Spectrum Disorders in Detail

• Rett’s Disorder:

  • Characterized by multiple deficits following a period of normal functioning; primarily affects girls.

• Childhood Disintegrative Disorder:

  • Involves marked regression in multiple functional areas after two years of normal development, often accompanied by nonspecific anxiety and agitation.

• Asperger’s Disorder:

  • Similar to autism but without language or cognitive delays; motor clumsiness is common and the disorder is more frequently diagnosed in boys.

Associated Disorders with Autism Spectrum

• Disorders related to autism spectrum include:

  • Tic disorders

  • Learning disorders

  • Motor skill disorders

  • Communication disorders

  • Elimination disorders

Tic Disorders

• Defined as rapid, sudden, recurrent, nonrhythmic stereotyped movements or vocalizations.

• Treatment options:

  • Atypical antipsychotics (e.g., olanzapine, risperidone)

• Tourette’s Disorder:

  • Involves multiple motor tics and at least one vocal tic.

• Chronic Motor or Tic Disorder:

  • Can involve either motor or vocal tics, not both.

Learning Disorders

• Defined as achievement below the expected level in:

  • Reading

  • Mathematics

  • Written expression

• Impact on:

  • Academic achievement

  • Life activities

  • Development of self-esteem and social skills

• Early identification and intervention are crucial for better outcomes.

Motor Skill Disorders

• Refers to developmental coordination disorder characterized by significant impairment in coordination that interferes with academic achievement or activities of daily living (ADLs).

• Often coexists with communication disorders.

• Treatments include adaptive physical education and sensory integration to foster growth and development.

Communication Disorders

• Communication deficits severe enough to hinder development, academic achievement, or activities of daily living (ADLs), including social interactions.

Types of Communication Disorders

• Expressive Language Disorder:

• Mixed Receptive–Expressive Language Disorder:

• Phonologic Disorder:

• Stuttering Disorder:

• Treatment often includes speech therapy to improve communication skills.

Elimination Disorders

• opresiEncs:

  • Involves defecating in inappropriate places, applicable for children at least age 4. Types include:

  • Involuntary encopresis

  • Intentional encopresis

• Enuresis:

  • Defined as repeated urination during the day or night in clothes or bed after age 5, most often involuntary. Intentional enuresis is associated with disruptive behavior disorders.

Attention Deficit Hyperactivity Disorder (ADHD)

• Characterized by a persistent pattern of inattention and/or hyperactivity-impulsivity, including:

  • Inattentiveness

  • Overactivity

  • Impulsiveness

• Symptoms manifest when a child begins school, including:

  • Fidgeting

  • Noisiness

  • Disruption of classroom activities

  • Difficulty completing tasks

  • Failure to follow directions

  • Blurting out answers

  • Frequent loss or forgetting of homework

  • Possible ostracization or ridicule from peers.

Etiology of ADHD

• The exact cause remains unknown, but several factors are proposed:

  • Cortical-arousal abnormalities

  • Information-processing issues

  • Maturational brain abnormalities

  • Environmental toxins

  • Prenatal influences (e.g., substance exposure)

  • Genetic/hereditary predispositions

  • Potential damage to brain structure and functions

• This disorder occurs across various cultures.

Treatment Goals and Strategies for ADHD

• Consensus exists that there is no single treatment effective for all individuals.

• Primary goals are:

  • Managing symptoms

  • Reducing hyperactivity and impulsivity

  • Increasing attention spans

• Combines medications with:

  • Behavioral interventions

  • Psychosocial support

  • Educational strategies

Home and School Strategies for ADHD

• Behavioral strategies utilized at home and school, including:

  • Environmental adjustments

  • Parental education on managing ADHD behaviors

  • Use of rewards and consequences to reinforce positive behavior

  • Daily report cards and point systems to track progress

  • Therapeutic and creative play approaches in activities.

Medication Options for ADHD (See Table 22.1)

• Stimulants:

  • Methylphenidate (Ritalin)

  • Amphetamine compounds (Adderall)

  • Lisdexamfetamine (Vyvance)

• Antidepressants as a second-choice option.

• Non-stimulant (SNRI):

  • Atomoxetine

• Antihypertensives:

  • Clonidine (Kapvay)

  • Guanfacine (Intuniv)

ADHD and Nursing Process Application

• Assessment includes:

  • Patient history showing difficulties since infancy (e.g., fussy behavior)

  • Observations of general appearance and motor behavior (e.g., inability to sit still)

  • Assessment of mood and affect, possibly indicating labile emotions, anxiety, frustration, agitation.

  • Evaluation of thought processes, sensorium, and intellectual capacities.

  • Self-concept assessment indicating possible low self-esteem related to challenges in major life areas (academic, social).

Data Analysis/Nursing Diagnoses

• Potential nursing diagnoses include:

  • Risk for Injury

  • Ineffective Role Performance

Outcome Identification Goals

• Establish outcomes such as:

  • Child remains free of injury

  • No violations of others' boundaries

  • Demonstration of age-appropriate social skills

  • Task completion to the best of their ability.

Interventions for ADHD

• Strategies to include:

  • Ensuring safety and minimizing risk factors

  • Enhancing role performance through supportive interventions

  • Simplifying instructions for clearer understanding

  • Promoting a structured daily routine to assist in organization

  • Providing education and support to patients and families regarding the condition.

Mental Health Promotion and Prevention Strategies

• Parenting classes to increase parental knowledge and skills.

• Child anxiety management programs.

• Parent-child interventions focusing on coping skills development.

• Use of early detection tools for identifying potential issues (e.g., SNAP-IV Teacher and Parent Rating Scale).

Nurse's Role in Health Promotion

• Importance of early detection and intervention to aid children with ASD (Autism Spectrum Disorders) in reaching their potential.

• Collaboration with various specialists is crucial, including:

  • School psychologists

  • Pediatricians

  • Physiotherapists

  • Teachers

  • Neurologists

  • Families

  • Speech therapists

  • Occupational therapists

Self-Awareness Issues

• Encouragement for practitioners to recognize their own beliefs about parenting and how they may differ from others.

• Emphasis on focusing on the strengths of both children and parents, rather than solely on issues.

• Importance of striving to have a positive impact on children regardless of severity of their disabilities.

• Support for parents to bolster their approaches and coping mechanisms.
